METHOD OF SYNTHESIS OF 1-ETHYL-2-PHENYLALUMACYCLOPROPANE Russian patent published in 2000 - IPC

Abstract RU 2152395 C1

FIELD: organic chemistry and chemical technology. SUBSTANCE: invention relates to method of synthesis of 1-ethyl-2-phenyl-alumacyclopropane of the general formula (I) that involves interaction of styrene with ethylaluminium dichloride EtAlCl2 and metallic magnesium taken in the mole ratio : EtAlCl2 : Mg = 10 : (10-12) : (10-12), respectively, in the presence of bicomponent catalyst consisting of cobalt dichloride CoCl2 taken in the amount 3-5 mole % with respect to styrene and triphenylphosphine (Ph3P) in the mole ratio = 1:(1-3). Reaction is carried out in argon atmosphere under normal conditions in tetrahydrofuran medium for 8-12 h. Proposed method ensures to synthesize the novel 1-ethyl-2-phenylaluma-cyclopropane that can be used as a component of catalytic systems in the process of oligomerization and polymerization of olefins and diene hydrocarbons and in industrial fine organic and metalloorganic synthesis also. EFFECT: improved method of synthesis. 1 tbl
